PCBs (Printed Circuit Boards), an Introduction

An electronic device is made by using several components like ICs, transistors, diodes, capacitors, resistors, displays, indicators, switches, buttons, connectors etc. All these are connected to other components according to a schematic. A printed circuit board helps hold all components of a device in one place as a single unit and at the same time provide required electrical connection between pins of components. Read more …

AVR Development Board – Assembly Instructions

A well designed development board is always essential for smooth development/experimentation with microcontrollers. Every hobbyist must have some kind of development setup. Some people use breadboard while others use veroboard to fabricate their development system. Many also use ready made off the self development board. Development is not very easy if you use only bread boards or veroboard. If you use bread board, after few days of use the wire will become loose or come out of hole. While making large circuit in a veroboard is a tedious job. To solve these problem I decided to make a low cost development board that has the following features. Low Cost All Basic connection required for developing application with AVR MCUs A Serial Port Prototyping area (like a veroboard) Incircuit Programmable with USB AVR Programmer Supports 40 PIN MCUs like ATmega16 and ATmega32. Buy Fully Assembled and Tested AVR Development Board So if you use this board, its lots easier. The basic circuit for MCU (like power supply,reset,ISP,serial port etc) are already done on a high quality PCB and some space is left for you to add other project specific components. You can also design other part of your project in bread board. But this time your bread board will be lot cleaner as major tested circuit is on the development board. […]
